Susumu Nakoshi
名越進
Susumu Nakoshi is a middle-aged man living in his car. Spending his time between a park full of homeless people and upper-class complex hotel, he is chosen by [Ito Manabu](https://anilist.co/character/8279/Manabu-Ito) to be an experimental guinea pig because he is neither an egocentric wealthy guy, nor a pitiful homeless man. He is "just between". After the Trepanation, he is able to see the "monster" in each human being, things that frighten or obsess people. By studying the human nature and facing the other's fear, he'll try to understand his own person thanks to this strange and worrying 6th sense. When he is stressed or depressed, he jerks off and eats his own semen to prove if he is still "alive".
